Enabling sFlow Globally on the Switch

Before the switch starts sampling packets for sFlow, you must enable sFlow globally on the switch.

Enable sFlow globally using the command:
enable sflow
Disable sFlow globally using the command:
disable sflow

When you disable sFlow globally, the individual ports are also put into the disabled state. If you later enable the global sFlow state, individual ports return to their previous state.
